Frequently Asked Questions?
Q: Does this include both turbochargers?
A: This Mercedes SL Class 221 S550 AWD engine from 2013 is a powerhouse designed for performance, but this listing includes the engine only—turbochargers are not part of the package. If you’re aiming for full boost, those turbos need to be sourced separately.
Q: Are engines tested for quality before shipping?
A: All our engines are carefully inspected by certified experts to ensure quality. They undergo tests for noise, leaks, and compression. We only offer top-grade, reliable engines.
Q: How does my engine arrive?
A: Your engine is securely shrink-wrapped and mounted on a 3x3 pallet, drained of all fluids. It ships safely via trusted carriers like FedEx, R&L, XPO, or YRC.
